FrostMEISTER hose with pressure gauge

Service hose with pressure gauge allows for precise and safe replenishment of refrigerant, helping to maintain the proper performance of the air conditioning system in the car. Manifold gauge sets are essential equipment during diagnostics and servicing of air conditioning systems, as they allow for monitoring the refrigerant pressure and quickly assessing the condition of the installation. With the pressure gauge readings, both low and high pressure in the system can be monitored, which facilitates proper filling, servicing, and ongoing control of the air conditioning operation. Using the appropriate measuring tools increases work safety and helps maintain optimal efficiency of the cooling system.

Indicators on the air conditioning gauge:

White color – indicates too low pressure in the system (below 25 psi).
In this situation, refrigerant should be added until the needle is in the green range. It is recommended to start by using a sealant, and only then to add gas.

Green color – indicates the correct operating range of the air conditioning (25–55 psi).
The system is functioning properly. If the needle drops back into the white area, it is recommended to use a sealant.

Red color – signals too high pressure in the installation (above 55 psi).
In this situation, the pressure in the system should be lowered according to the service procedure.

If your vehicle requires R1234yf gas, in addition to the hose, you will also need an R1234yf valve adapter. You can buy it here.
